Buffer shortage management system

An information handling system, comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a buffer shortage management engine that is configured to:
• determine that a total buffer pool utilization of a buffer pool in a buffer, which identifies a utilization of the buffer pool by a first data flow, a second data flow, and at least one third data flow, has reached a first buffer pool utilization threshold that affects the first data flow that is received through a non-Link Aggregation Group (LAG) port;
• identify that the second data flow and the at least one third data flow are received via a LAG and through at least one LAG port, wherein the second data flow is received from a connected networking device via the LAG and through the at least one LAG port;
• determine that the second data flow has a higher relative utilization of the buffer pool than any of the at least one third data flows;
• and
• transmit, in response to determining that the second data flow has a higher relative utilization of the buffer pool than any of the at least one third data flows, a buffer shortage notification to the connected networking device that is configured to cause the connected networking device to redirect the second data flow such that the second data flow is not received via the at least one LAG port.

A method for managing buffer shortages, comprising:

• determining, by a first networking device, that a total buffer pool utilization of a buffer pool in a buffer in the first networking device, which identifies a utilization of the buffer pool by a first data flow, a second data flow, and at least one third data flow, has reached a first buffer pool utilization threshold that affects a first data flow received through a non-Link Aggregation Group (LAG) port on the first networking device;
• identifying, by the first networking device, that the second data flow and the at least one third data flow are received via a LAG and through at least one LAG port on the first networking device, wherein the second data flow is received from a second networking device the LAG and through the at least one LAG port;
• determining, by the first networking device, that the second data flow has a higher relative utilization of the buffer pool than any of the at least one third data flows;
• and
• transmitting, by the first networking device and in response to determining that the second data flow has a higher relative utilization of the buffer pool than any of the at least one third data flows, a first buffer shortage notification to the second networking device that causes the second networking device to redirect the second data flow to a third networking device.
